Abstract: A cutting device for the chipless cutting of a material comprises a cutting part and a supporting part. The cutting part and the supporting part are designed to be rotated with respect to one another about an axis of rotation between an open position and a closed position. A hand lever is articulated to the supporting part for pivoting about a pivot axis. A ratchet mechanism converts a back-and-forth motion of the hand lever into a continuous rotational motion of the cutting part toward the closed position. The ratchet mechanism includes a toothing and a drive pawl, which can be brought into an effective position with respect to the toothing. Furthermore, the cutting device comprises a coupling mechanism, which converts a one-time pivoting motion of the hand lever into a rotational motion of the cutting part. A separate coupling element transmits force from the hand lever to the cutting part.
